Lenovo to show six new desktop PCs at CES

Lenovo will bring six desktop computers to CES this week, including four IdeaCentre all-in-ones from the B-series, the easily upgreadable H520s and the slim IdeaCentre K430. The IdeaCentre B540 uses a 23-inch frameless touchscreen with 1080p resolution and an integrated VESA mount that can be equipped with 3D capabilities. It can be equipped with NVIDIA's GeForce GT 650M graphics card with 2GB of RAM and DirectX 11 support.

The smaller, 21.5-inch B340 will also sport a 1080p touchscreen and likely many of the same processor choices as the B540. Both can be optioned with a OneKey TV feature that will switch between PC and HDTV functionality with one button. TV can be watched without the PC running at all. A 720p webcam is integrated into either, and a DVD reader is standard, with a Blu-ray drive on the options list. They are expected to ship in June, starting at $700.

The B480 and B580 will offer "essential" computing and start at $400 when they ship in April. Not muh was revealed about tech specs, other than that they will offer Intel Core i3, i5 or i7 Ivy Bridge chips or those from AMD's Fusion line-up. NVIDIA's Optimus graphics cards will be optional.

The H520s will take up half the space of a conventional desktop, Lenovo said. It promises to be easy to use, thanks to the Lenovo Assistant interface. Power will come from a choice of Intel Core processors and AMD Radeon or NVIDIA GeForce video processing hardware. It's due to ship in June, starting at $500.

Finally, the IdeaCentre K430 can be upgraded right from Lenovo, offering as much as 4TB of storage space from hard drives or a 128GB SSD. The PC also includes a Universal Storage Module (USM) dock and a 500GB portable hard drive to match. It will use unspecified Intel Core processors and can be optioned with up to 32GB of RAM. Dual graphics support is ensured and users can select three color-coded speed programs by pressing the Power Control Switch. The K430 is said to ship in May, with prices starting at $600.
